Remember, a screamer will NOT even begin to activate until the impact force exceeds 500lbs. Once the load goes below 500lbs it stops ripping (i.e. it can only partially extend/rip)
Now imagine this. Your harness has 2" webbing right? That means you would bear the impact over a 2" section of your ribcage and or spine. Would you sign up for having your ribs/spine whacked with the narrow side of a 2x4 to the tune of >500lbs??? That'd be about the same as standing there while Babe Ruth took his best swing at your ribcage!
If you loose your balance and get snatched up against the tether with the screamer, it's no big deal. If you fall far enough across the boat to activate the screamer, you're REALLY going to want it to activate to avoid major bone and organ damage.
